SWITCHING REGULATOR SECTION AGND1 31 – Analog ground connection. All analog ground pins are connected internally on the chip. AGND2 13 – Analog ground connection. All analog ground pins are connected internally on the chip. Input signal indicating default VDCDC1 voltage, 0 = 2.80 V, 1 = 3.3 V 9 I DEFDCDC1 This pin can also be connected to a resistor divider between VDCDC1 and GND. In this case the output voltage of the DCDC1 converter can be set in a range from 0.6V to VINDCDC1 Input signal indicating default VDCDC2 voltage, 0 = 1.8 V, 1 = 2.5 V 22 I DEFDCDC2 This pin can also be connected to a resistor divider between VDCDC2 and GND. In this case the output voltage of the DCDC2 converter can be set in a range from 0.6V to VINDCDC2. Input signal indicating VDCDC3 voltage. TPS650240: 0 = 1.0 V, 1 = 1.3 V TPS650241: 0 = 0.9 V, 1 = 1.375 V DEFDCDC3 32 I TPS650242: 0 = 1.0 V, 1 = 1.5 V TPS650243: 0 = 1.0 V, 1 = 1.2 V TPS650244: 0 = 1.55 V, 1 = 1.6 V TPS650245: 0 = 0.9 V, 1 = 1.1 V EN_DCDC1 20 I VDCDC1 enable pin. A logic high enables the regulator, a logic low disables the regulator. EN_DCDC2 19 I VDCDC2 enable pin. A logic high enables the regulator, a logic low disables the regulator. EN_DCDC3 18 I VDCDC3 enable pin. A logic high enables the regulator, a logic low disables the regulator. L1 6 – Switch pin of VDCDC1 converter. The VDCDC1 inductor is connected here. L2 27 – Switch pin of VDCDC2 converter. The VDCDC2 inductor is connected here. L3 3 – Switch pin of VDCDC3 converter. The VDCDC3 inductor is connected here. PGND1 7 – Power ground for VDCDC1 converter PGND2 26 – Power ground for VDCDC2 converter PGND3 2 – Power ground for VDCDC3 converter PowerPad – – Connect the power pad to analog ground 4 Submit Documentation Feedback Copyright © 2007–2016, Texas Instruments Incorporated Product Folder Links: TPS650240 TPS650241 TPS650242 TPS650243 TPS650244 TPS650245 |
